To aZZ whom it may concern This invention relates to concrete buildings, particularly to molds therefor, and has for its object the provision of a concrete wall mold which is so constructed as to produce a very strong wall having vertically extending channels which form ribs materially reinforcing the structure.

An important object is the provision of a mold of this character which includes the use of nailing strips wedgingly engaged between'successive portions of the mold and carrying headed members to be embedded within the plastic materialwhereby the nailing strips will become a permanent part of the wall andremain associated therewith when the mold is removed, these strips being for the purpose of providing attaching means for the interior trim. v

Another object is the provision of a device of this character in which the nailing strips are mortised forthe reception of sills for holding the floor joist or the roof rafters, as maybe found requisite.

A further object is the provision of a mold of this character which includes the use of a plurality of trough-shaped members arranged in spaced relation and adapted to define between them vertically extending ribs which reinforce the wall structure, the nailing strips being carried bythe edges of these ribs, other means being provided for preventing caving in of thetrough-shaped members when the sections of the mold are secured together.

An additional object is the provision of a mold of this character which will be simple and inexpensive in manufacture, highly efficient in use, durable in service, and a general improvement in the art.

Vith the above and other objects and advantages in view, the invention consists in. the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- Y Figure 1 is a perspective view of a portion of the outer mold member looking at the rear side thereof,

Fig. 2 1s a perspective v1ew of the inner and outer sections of the mold in assembled relation,

Fig. f is a perspective view of a wall formed by my mold and showing the mold removed,

Fig. 5 is a perspective view of one of the is a cross sectional view theretrough shaped members constituting a portion of the inner mold member,

Fig. 6 is a cross sectional view through the completed wall, and y Fig. 7 is a perspective view showing the treatment around doors and windows;

Referring more particularly to the drawings, the numeral 10 designates broadly the outer mold member which is formed by a plurality of vertical and transverse bars 11 which in actual practice would be picc of 2 r: 4 scant-ling suitably nailed or seen getherand reinforced if necessary, by suit able diagonal brace members, not shown. Upon one side the frame, formed by th pieces of 2 X 4C is covered by a sheet or sheets '12 of sheet metal, preferably galvanized iron. It will be observed that any suitable number of units constructed in this manner may be connected to form a continuous mold structure.

T he inner mold comprises a suitable frame 13 formed of piecesl l of 2 X scantling of any desired number and arrangement and suitably secured. Disposed against the inner frame 13 are trough-shaped members 15 vertically arranged and formed also. preferably of galvanized ironand these trouglr' shaped members are arranged in slightly spaced relation with nailing strips 16 d sposed between them and having slightly inclined edges'conformingly engaging the in clined sides of the trough-shaped members and these nailing strips 16 are formed. of wood and having extending from them headed fasteners 17 such as nails which have their heads disposed in spaced relation. to the strips, as clearly shown in 3, so that 'these heads will be embedded within the plastic material poured between the outer and inner molds. Disposed within each trough-shaped member 15 and lying against the inner is a vertically extending strip 18 and against this strip is disposed at intervals, a' block 19. The outer and inner frames 10 and 13 are connected at suitable intervals by bolts 20 which pass. through these members, through the strips 18,

through the block 19, and also through circular washers 21, formed preferably of concrete, disposed between the sheet 12 and the trough-shaped members 15. i

It is of course to be understood that the outer and inner mold members are formed in units adapted to be secured together in juxtaposition to form any length or height of wall, the corners being constructed as found preferable. The outer and inner mold members being arranged in position, the

space between them is filled with concrete which is allowed to set. After the concrete is set the outer and inner mold members are removed which will leave the strips 16 secured to the wall designated by the numeral 22 in Fig. iand Fig. (:3 and it will also leave the concrete washers 21 embedded within the wall. it is of course apparent that'the purpose of these washers is merely to space the outer and inner mold members apart. ll hen the molds are properly constructed and arranged it will be apparent that all four walls of a house may be poured at the same time. i

Referring particularly to Fig. 7, it will be seen that I have provided several treatments for windows or other openings in the wall.

In this form it will be seen that the nailing strips 16 are cutaway or recessed, as shown at for thereception of sills 24 adapted to support floor joists or roof rafters, as the case may be. It will also be observed that at the top of the wall I provide a plate or plates 25 which may support roofrafters or.

beams, if preferred. Another feature is that i provide suitable plates 26 and 27 at the vertical and horizontal edges of any desired opening to be made in the wall so that when the cast is made openings will be defined in the wall.

In the construction of walls I prefer to place 1 between the outer and inner mold m mbers vertical and horizontal reinforcing ro s28 and 29, respectively, which are held in position by any suitable means. When the cement is poured it is of course apparent that these rods will be embedded therein, as

member.

clearly shown in Fig. 4, so as to provide a very strong and durable wall structure.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed and consequently inexpensive mold structure whichis readily adapted for connection for forming walls, which is provided with strips to be embedded partially within the molded wall whereby to provide means for securing the interior trim, and which will be a general improvement in the art.

lVhile I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the rightto make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

A cement wall mold comprising outer and inner frames, a plurality of separate vertically disposed trough shaped members disposed with their edges agai the outer side of the inner frame with their bight portion of the trough members, spacing washers CllSPOSGCl between the outermost portions of the trough shaped members and'the inner face of the outer frame, and tie bolts passing through both frames, through said spacing washer,

In testimony whereof I affix my signature.
